In this paper, the analysis and design of a switch-mode DC-DC boost converter with a feedback control for a solar battery charging circuit are presented. The design of a feedback control for such converters is desired to ensure an output with zero steady state error and fast response to input/output voltage and load changes. To achieve these characteristics, a fixed frequency compensated voltage-mode controller is designed and implemented for a DC-DC boost converter operating in Continuous Conduction Mode (CCM). The proposed controller addresses the issue of moving Right-Half-Plane (RHP) zero of a boost converter caused by variations in the input voltage of solar panel and load. The designed controller is fast, robust, and does not have the complexity of current available strategies for battery charging circuits. The simulation studies are provided to evaluate the performance of the proposed approach.
